Dc. Duffy et Sr. Campbell, AMBIENT AIR-TEMPERATURE AS A PREDICTOR OF ACTIVITY OF ADULT IXODES-SCAPULARIS (ACARI, IXODIDAE), Journal of medical entomology, 31(1), 1994, pp. 178-180
Based on winter flagging experiments on Long Island, NY, adult Ixodes
scapularis Say have an apparent threshold of questing activity at 4-de
grees-C. This threshold should be incorporated into public education e
fforts because the public may be at risk of contracting Lyme disease a
ny time during the winter when temperatures exceed 40-degrees-C.
